6 Pin into 8 pin motherboard???

[syedfazalshah2]

I have B250 Mining Expert Motherboard and the power supply imported from China.
My question is that I am trying to connect my power supply 6+2 pin cable to the motherboard's 8 pin but only the 6 pin connects and 2 pin doesn't.
I wonder if I have to use a Converter or I can use only 6 pin which fits well.

Make and model of your PSU? Are you trying to connect the PCIe 6+2pin to your motherboard's 8pin EPS connector? If so stop right there and make sure you've got a 4+4 pin EPS or a proper 8pin EPS connector. You're not going to be able to get anything done with the 6 pin in the place of a 8pin EPS connector.

If the PSU doesn't have the necessary connectors, you've got the wrong unit for the job.

No, the 6+2 pin is for pcie supplementary power, it's for GPU power basically the 8 pin on the mobo is for cpu power. Your power supply should have either a 4+4pin or a 4pin for cpu power, use that. If your power supply has only a 4pin you will need to look in your mobos manual for which side of the 8pin connector to put the 4pin from the power supply in.

Sorry I can't tell the model as it's Chinese made!!
Yes you are right those are PCIE pins and won't fit well.
I didn't plugged into the pins and thanks for stopping me.
Can you suggest a converter which converts the 6+2 pin to 4+4(EATX12V) for my mobo.

That doesn't matter. Chinese PSUs also have model names.
Can you post photo of PSU label?

this power supply is not a regular motherboard PSu, its a mining rig power supply design to power 5-10 video cards only.
there is no 24 pin or 4+4 Connector on that PSU what so ever

You would need this type of adapter: PCIE to EPS 8 (4+4)pin.

Much appreciated but it says 6 pin to 4+4 is that okay??

Mine PSU has 24 pinm I'll post the link to psu.

Yes it's fine.
You probably will not be putting high power cpu (like i7-7700k) in that board anyway.

That adaptor will be fine, as SkynetRising say, you are probablt using low end CPU Intel G series.

Off topic - but this is why I think that the 24 pin connector which is already 20+4 should just be 32 pin - we have got to start phasing out old standards and keep everything upto date. Technology moves fast, but motherboard standards are stagnant.

^ well no I'd disagree 100% with that, the 4+4 pin atx has always been a separate entity because it's carrying the majority of 12v power required for the cpu.

Hence why the atx socket is always in close proximity to the vrm's.

Otherwise your need to relocate entire 32 pin connector you suggest to the top left of the board too (where there is little room as it is) or have 4 x 1/2 inch wide heavily insulated traces running from a single 32 pin socket all the way across the board to the vrm setup.

The way it is is like it is for that reason.

Yeah I won't because I'm not doing cpu mining however If I'm not able to find this specific converter, I can use another PSU isn't it? If so, what wattage should be enough to power the board and CPU and other stuff like RAM and SSD???
Is 350 WATT enough??

I can't accept what you say, because the PSU has a 30cm cable for the 4+4 connector, so the voltage has already travelled 30cms. So your arguement, while valid to a certain point, is invalid because its already gone 30cms from the PSU itself.

The 20+4 connector can easily be moved to where they want it on the board, and combine it with the 4+4 making a 20+4+4+4 connector - which still seems outdated because they keep adding to it.
